110 AMERICAN FERN JOURNAL 
drained, the majority of the species of plants belonging 
to the Ericads. The trees are Larix laricina, Thuja 
occidentalis, Picea canadensis, Picea mariana and Taxus 
canadensis. The floor of the densely covered bog con- 
sists of several species of Sphagnum and only in the open 
and more or less partially cleared areas are the sedges, 
grasses and liliaceous plants to be found. The trails 
which were cut through the bogs by the lumbermen 
represent about the only regions where the ferns grow 
in any abundance. Sometimes they are to be found 
rather plentifully along open streams which penetrate 
the bog. The fern seldom migrates far into the densely 
shaded areas and but few of the hardwood species are 
found. The most common species to be noted was the 
Aspidium thelypteris which does not occur in the hard- 
woods. Of the Osmundas, regalis and cinnamomea were 
found in considerable abundance in nearly all the bogs 
and usually in the more open areas. Osmunda Clay- 
toniana was never seen by the writer in this region but 
was reported by Professor Smith from Smith’s Bog. 
Scattered throughout the bog were Aspidiwm cristatum, 
Phegopteris polypodioides, Phegopteris dryopteris, Aspid- 
wum noveboracense, Botrychium virginianum and, in 1914, 
Ophioglossum vulgatum was found for the first time. No 
other species have been found since the discovery of this 
fern and yet it is quite possible that some species have 
escaped the eyes of the investigator. Botrychium vtr- 
ginianum was the most abundant in the shady areas 
and presented a great range in size. The smallest of 
them were not more than 10 em. high and at times were 
difficult to distinguish from mature Botrychium simplex 
which did not grow in this region. Another striking 
feature concerning Botrychium virginianum was that it 
was just as likely to be found growing in the richest 
o woods to a height of three feet as it was in the cold bogs 
ae. = the soil was Lexie acid and cold. :
